Grok 4.7 is xAI's best model for writing — it scores 85/100 vs 84/100 for Grok 4.6, at $2/1M input tokens. Across all providers, Claude Sonnet 5.5 still leads writing at 98/100 — worth considering if you're not committed to xAI.
The safest xai model for writing default, the cheaper option worth trying first, and the specialist pick — before you read the detail below.
Grok 4.7 is the strongest answer here for xai model for writing — pick it when quality of output matters more than the $2.00/1M/1M input you pay for it.
Claude Sonnet 5.5 is the cheaper way in for xai model for writing, at $2.00/1M/1M input against Grok 4.7's $2.00/1M/1M.
Grok 4.6 is the fastest of these for xai model for writing — worth it when latency is what the reader notices, not the last few points of reasoning depth.
Grok 4.7 leads xAI's lineup for writing at 85/100 ($2/1M input, 500K context).
Grok 4.7 is the value pick at $2/1M input with a writing score of 85/100.
Claude Sonnet 5.5 (Anthropic) is the overall writing leader at 98/100 if provider choice is open.

Why each one is on the shortlist for xai model for writing, what it is genuinely good at, and where we would steer you away from it.
Ranked first here for xai model for writing: 87/100 on coding, with the widest margin of anything in this line-up.
Grok 4.7, released September 21, 2026, targets coding and professional knowledge work over multi-hour tasks, with better self-verification and long-context handling than Grok 4.6 at the same $2/$6 price.
You need a published SWE-bench score, or predictable cost per task — independent testing found its token use roughly doubled.
An incremental update. Grok 4.7 keeps Grok 4.6's price and gains a little on coding-quality tests, but independent runs found it spending far more tokens per task. Worth testing if you are already on Grok; not a reason to switch.

Here for latency: it answers fastest of anything listed for xai model for writing, at 86/100 on coding.
xAI's long-horizon agent model — it finishes agentic tasks in roughly half the turns of its rivals, which makes it cheaper in practice than its per-token price suggests.
You need a published SWE-bench score to justify the pick, or your prompts routinely cross 200K tokens where the price doubles.
Superseded: Grok 4.7 (September 21, 2026) keeps the same price. Buy it for turn efficiency, not for benchmark ceilings. On long agent runs, finishing in half the turns beats a model that scores two points higher and takes twice as many round trips.

Grok 4.7 — it scores 85/100 on writing in this directory, ahead of Grok 4.6 at 84/100. Grok 4.6's price with modest coding gains and heavier token use.
Not overall. Claude Sonnet 5.5 (Anthropic) leads the directory for writing at 98/100 vs Grok 4.7's 85/100. Grok 4.7 is the best pick if you're staying within xAI's ecosystem.
Grok 4.7 at $2/1M input tokens (writing score: 85/100). Use it for volume work and reserve Grok 4.7 for the tasks where quality matters most.
$2/1M input tokens and $6/1M output tokens via the API, or through SuperGrok at $30/mo for chat use. Context window: 500K tokens. On a moderate month — 10M input and 2M output tokens — that works out to about $32.00, against $32.00 for Grok 4.7.
No published SWE-bench Verified or Pro figure, so it is absent from our SWE-bench leaderboard. Trails Claude Fable 5.1 on the vendor's own coding and terminal rows (Terminal-Bench 4.0 37.6%). Concretely, avoid it if you need a published SWE-bench score, or predictable cost per task — independent testing found its token use roughly doubled. If none of that is negotiable, Claude Sonnet 5.5 (Anthropic) is the cross-provider leader at 98/100.
long coding sessions where the model checks its own work before handing back, document and presentation drafting as part of a longer task, and research agents working through a topic across many steps. Its 500K-token context window is the practical limit on how much you can hand it in one go.
They are the same model here — Grok 4.7 is both xAI's strongest writing pick and its best value, so there is no trade-off to make.
